STUDY ON FRACTAL OF FAULTS SYSTEM IN THE NANPU SAG,JIDONG
冀东南堡凹陷断裂系统分形研究

According to figure of faults distribution in the bottom of Minghuazhen formation of nanpu sag, self-similarity of fault spatial distribution has been examined by using fractal theory and the fractal dimension of capacity. Correlation coefficients are between 0.99 and 1, which suggests that faults are fractal structure. The fractal dimension of capacity(D_(0)) in different areas have been calculated and its isoline map is drawn. Author find that the three of four oilfield are located in the areas where the fractal dimension of capacity are larger than 1.18, which show that the distribution of the fractal dimension relates to the distribution of oilfield. So Beipuxi fault zone, nanpu fault zone and getuo fault zone are ascertained as the favorable areas.
